Have shot a Vinci for three seasons now at the Wister Wildlife Refuge. About 11 hunts per season. Have had only one shell fail to eject properly. I'd like to think that's a pretty good record given the sticky clay soil and salty conditions there. No rust to boot. Go for the camo model, it gives you extra protection against the elements.

Personally, I prefer camo for a duck gun. The camo dip is a (small) layer of protection. That being said, I don't care for the Vinci. I think Benelli makes fantastic guns, but the Vinci is just too modern looking for me. That being said, the ducks don't care what you shoot, so if it appeals to you go for it. I have a friend who shoots one, and he loves it. That being said, I use an SX3, and their are plenty who don't care for it.
